P0340, P0016, P0017, P0365 Codes on 2012 Ford Fiesta

Question

2012 Ford Fiesta SE throwing codes: P0016, P0017, P0340, and P0365. No visible wire damage. Recommended to checking timing on timing belt to rule out the belt, and if that is fine, to next check the cam shaft sensors. Finally, if those are all fine, I was recommended to check the crank shaft sensor, which I was told was a cumbersome process. Any ideas?
Symptoms: CEL on, and during start up there is a slight shudder or sort of skip, then it will turn on, or it may just not fully start and I'll have to turn the key to start the engine again.

Answer 1

P0016 Crankshaft position -camshaft position Bank 1 sensor A

P0017 Crankshaft position-camshaft  postion Bank 1 sensor B

P0340 Camshaft position Sensor A circuit (Bank1 )

P0365 Camshaft position sensor B circuit (Bank 1)

It is better to rule out a mechanical problem dealing with the timing belt area. This engine is out of timing. If this was a variable camshaft timing solenoid or even the cam position sensor the engine will start up but there would not be a shudder or a skip at idle. it would run rough on engine load. Rule out a mechanical condition
